A couple weeks ago, my rear glass randomly shattered on me. At the time i had no idea what caused it. After thinking of things like, chassis flex, pressure change (going down a steep hill when it happened), and air temp. (cold as a mug in NY), i found out upon replacing the glass that the nodes the electronic line to my defroster were burned out. Now..what could be the cause of this? I was told there's a voltage limiter that shuts off the heater at a certain temp..could that be fried? Anyway, anyone with any ideas, speak up please.

 

no one knows?
